Canonical has published the official release schedule for Ubuntu 26.10, codenamed Stonking Stingray, and the date is set. The next interim release of Ubuntu lands on October 15, 2026.
The schedule was made public today, May 10, 2026, and development work on the new cycle is already underway. Work on 26.10 did not wait for the schedule to be announced.
The Ubuntu development team began uploading toolchain packages to the 26.10 archive on April 30, 2026, just one week after Ubuntu 26.04 LTS shipped. That includes updated versions of GCC, binutils, and glibc, the foundational build tools that underpin every package in the repository.
This early toolchain work sets the baseline that all other package maintainers build against as the cycle progresses.
Ubuntu 26.10 is an interim release, not an LTS. That distinction matters for users deciding when and whether to upgrade. Interim releases carry nine months of security and maintenance support, compared to five years for an LTS. Ubuntu 26.10 will reach end of life in July 2027.
Users on Ubuntu 26.04 LTS who prefer stability and long support windows have no obligation to upgrade. The 26.10 release targets users who want access to the latest software as soon as it arrives, and serves as the development platform for features that will eventually land in the Ubuntu 28.04 LTS cycle.
On the desktop side, Ubuntu 26.10 is expected to ship GNOME 51 as its default environment. GOME 51 is on its own upstream release schedule. The alpha is due June 27, beta on August 1, release candidate on August 29, and stable release on September 12, just three weeks before Ubuntu 26.10’s final freeze on October 8.
That tight overlap between GNOME 51 stable and the Ubuntu final freeze is normal for interim Ubuntu releases, and the Ubuntu desktop team has managed this rhythm reliably for many cycles.
The kernel story is less certain but worth watching. Based on the historical interval between Linux kernel major releases, Ubuntu 26.10 is a candidate to ship Linux kernel 7.3. The Linux 7.1 development cycle is currently in progress, with the stable release expected in June 2026.
Linux 7.2 would follow roughly in August or September. If the 7.3 merge window opens and closes before Ubuntu 26.10’s kernel freeze on October 1, there is a plausible path to 7.3 landing in the release. Nothing is confirmed at this stage. The kernel freeze date is the clearer anchor: whatever stable or release candidate kernel is most current by October 1 is what ships.
AI features are the most talked-about topic on the Ubuntu 26.10 horizon.
Canonical’s Jon Seager outlined the company’s AI integration direction for Ubuntu in a community post earlier this month. The plan covers local inference using open-weight models, implicit features like improved accessibility speech tools, and explicit features such as document writing assistance.
According to discussion on Ubuntu Discourse, these AI features will not be enabled by default in Ubuntu 26.10 and will be configurable during the setup process. The full AI implementation is expected to take shape over multiple releases rather than arriving complete in a single cycle.
The key dates in the Ubuntu 26.10 schedule are as follows. Feature Freeze and Debian Import Freeze fall on August 20. The Ubuntu 26.10 Beta releases on September 24. Kernel Feature Freeze follows on October 1. Final Freeze is October 8. The release itself is October 15, 2026.
The Ubuntu development team has also indicated that up to four monthly snapshot ISO builds may be published between May and August, giving testers early access to in-progress builds without waiting for the formal Beta. These snapshots are not mentioned in the official release schedule and carry no support guarantees, but they provide a useful way to track progress during the development cycle.
Canonical has also published forward-looking release plans for Ubuntu 27.04 and Ubuntu 27.10 in the Future Releases section of the official documentation. Those timelines are available alongside the 26.10 schedule at the official Ubuntu 26.10 release schedule page.
